I used to have the same SSD and sold it on eBay. It is a decent SSD based on the SMI controller (Model number ends with XXXMS). Power consumption is good due to native PATA controller but if you do some really heavy duty work, it will still slow down (but not stutter). I prefer the Eastwho controller but they are at least 50% more for the same capacity. Overall a good budget SSD for old laptops. I think on Windows XP it will work pretty well. On Windows 7/8 it will be hard pressed to provide sufficient performance to keep up with the OS demands.
